Abstract

A labeling machine for labeling a plurality of containers is disclosed. The labeling machine includes a loading mechanism that sequentially receives containers and discharges containers in a spaced relationship. A star wheel has a plurality of receptacles disposed about the periphery of the star wheel, and is rotatable around an axis of rotation. The star wheel sequentially receives containers from the loading mechanism. The receptacles are pivotally secured to the star wheel for limited radial and pivotal movement. The receptacles have a leading end and a trailing end relative to the direction of rotation of the star wheel. A label dispenser including a label holder is disposed adjacent the periphery of the star wheel. The label has a decorated side facing the dispenser and an adherent side facing the star wheel. Each container is fed by the loading mechanism to one of the receptacles that grips the container as it is rotated around the star wheel until it reaches a pick-up point where the container contacts the adherent side of the label causing the label to adhere to the container. The leading end and trailing end of the receptacle alternately extend radially and retract radially to adjust for changes in a contoured surface of the container relative to the axis of rotation of the star wheel as the star wheel rotates the container past the label dispenser.
